  • format_align_leftDescription
    Multi-purpose outdoor unit for use in 4-pipe systems for the simultaneous production of chilled and hot water by means of two independent hydronic circuits. These units are able to satisfy the demand for hot and cold water simultaneously through a system that does not require seasonal switching and is therefore a valid alternative to traditional plants with chiller and boiler. This unit is equipped with hermetic rotary Scroll compressors, with R410A, axial fans, shell and tube heat exchangers and electronic expansion valve. The range is composed by units equipped with four, six and eight compressors in multi-circuit configuration.

    Versions

    • B - Basic
    • CA - Class A of efficiency
    • SL-CA - Super Low noise version, Class A of efficiency

    Features

    • REFRIGERANT GAS R410A
      The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0)
    • UNIQUE PROPOSAL
      Unit designed to satisfy the cold and the hot side requirements simultaneously, for 4-pipe systems without any particular operation mode setting
    • ENERGY SAVING
      Energy saving guaranteed by the advanced operation’s logic. The best operation mode is set completely automatically and independently by the unit’s controller, in order to minimize the absorbed energy whatever the cooling and/or heating demand might be
    • CLASS A EFFICIENCY
      The full range is also available with the Class A efficiency rating (in heating). CA and SL-CA versions guarantee premium levels of efficiency thanks to the generous sizing of the refrigerant-exchange surface areas and to an accurate control of the fans, available on both standard and low-noise versions.
    • INTEGRATED HYDRONIC GROUP
      The built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line pump, for achieving low or high head, available for both hot and cold water distribution systems (up to 4 pumps).

    Accessories

    • Remote control keyboard (distance to 200m and to 500m)
    • Soft starters
    • Set-up for remote connectivity with ModBus, Echelon LonTalk, Bacnet protocol board
    • LT kit for extending the operating limits in heat pump mode down to -10 °C (/SL-CA versions) and -12 °C (/CA versions)

    Control

    • W3000SE Large
      The W3000SE Large controller offers advanced functions and algorithms. The keypad features an easy-to-use interface and a complete LCD display, allowing to consult and intervene on the unit by means of a multi-level menu, with selectable language setting. The regulation operates on both water circuits featuring the step-wise regulation referred to the return water temperature with proportional logic. This allows to satisfy simultaneously the different requests of both cooling and heating, with no need of mode setting. The diagnostics includes a complete alarm management, with the "black-box" and alarm logging functions for enhanced analysis of the unit operation. For multiple units’ systems, the regulation of the resources, via optional proprietary devices, can be implemented. Energy metering, for both consumption and capacity, can also be developed. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet, Bacnet-over-IP, Echelon LonWorks. Compatibility with the remote keyboard managing up to 10 units. Availability of an internal real time clock for operation scheduling (4-day profiles with 10 hour belts). The defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
